Patent CA-2065673-A1 (CA)
Title: Preignition warning device
Inventor: SEITZ WILLIAM R
IPC: G01M15/04
Filed: 1992-04-09
Abstract: ABSTRACT OF THE DISCLOSURE        A device for and method of providing reliable audible and visual warnings of incipient preignition in a combustion chamber is disclosed.  The current flow through at least one engine spark plug is monitored at specified times throughout a number of engine revolutions during which there should be no current flow and both an audible alarm and a visible alarm are activated in the event the monitored current flow exceeds a predetermined threshold. Circuitry establishes time intervals during which there should be no current flow through the monitored spark plug and additional circuitry temporarily provides both an audible alarm and a visible alarm for each occurrence of the monitored current exceeding the predetermined threshold.  Such a temporary alarm typically has the same duration as the detected excess current.  There is also circuitry for continuously enabling both the audible and visible alarms in the event of an excessive number of excessive monitored current flows within a specified length of time.

Title: Gravity flow thermal process for reclaiming foundry sand
Inventor: ROTHSCHILD JOHN J
IPC: B22C5/00
Filed: 1992-05-01
Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus for thermally reclaiming used foundry sand is disclosed.  The apparatus includes a vertically disposed furnace having a combustion chamber therein.

Disposed immediately below the furnace is a sand retention chamber in which the sand is accumulated.  Heated air is introduced into the retention  chamber  to  maintain  the  combustion  supporting environment.  Residual coatings remaining on the sand particles are thermally removed in the retention chamber.

Title: Retractable electric cord reel assembly
Inventor: KUHAR WILLIAM F JR
IPC: B65H75/42
Filed: 1992-06-17
Abstract: RETRACTABLE ELECTRIC CORD REEL ASSEMBLY                 ABSTRACT OF THE DISCLOSURE    A retractable cord reel assembly for an electric cord comprises a mounting bracket having an axle extending there-from and a spool  rotatably mounted on the axle.  The spool has a hub, and the hub has a keyed opening extending axially into the hub. A cord retainer assembly receives one end of the electric cord which is adapted to be word on the spool for storage. The cord retainer assembly slides into the keyed opening to be lockingly retained therein.  The cord retainer assembly, with attached cord, may be separately inventoried since the cord does not need to be connected to the spool when the cord reel is assembled or when the cord reel is mounted on the appliance or other device.   The cord can be subsequently assembled with the cord reel assembly at a later time.

Title: Inflation system for a balloon catheter
Inventor: ZYTKOVICZ DUANE
IPC: A61F2/958
Filed: 1991-10-21
Abstract: An inflation system for pressurization and depressurization of a balloon catheter. The inflation system includes a syringe (12), including a syringe barrel (14), a plunger (16) with expandable thread (66a-d), a handle (18) with cam, a syringe end cap (20), pressure gauge (22), flexible tubing (24), and connectors. The syringe is structured such that part of the syringe barrel has an internal thread which engages the expandable threads of the plunger.  In the disengaged mode, the plunger slides freely within the syringe barrel allowing for rapid motion to purge, pressurize, or depressurize the inflation system. Once pressure reaches a predetermined level in the system, the cam on the handle causes the threads to automatically lock against the syringe barrel, and continued pressurization or depressurization is accomplished by the rotation of the plunger handle with respect to the syringe barrel. One advantage of the inflation system is that only one step is necessary for locking the syringe for controlled pressurization and depressurization.

Title: Vehicle detector with automatic sensitivity adjustment
Inventor: HOEKMAN EARL B
IPC: G08G1/042
Filed: 1992-07-02
Abstract: VEHICLE DETECTOR WITH AUTOMATIC                SENSITIVITY ADJUSTMENT ABSTRACT OF THE DISCLOSURE A vehicle detector in which the sensitivity is adjusted by first measuring the period Tnv of an oscillator signal produced by an oscillator whose frequency varies as the inductance of an inductive sensor changes.  That inductance is in turn changed by a vehicle entering a detection area.  A number Nmeas of cycles of the oscillator signal, representing a measurement period, is then determined based upon the measured oscillator period Tnv and upon a desired minimum change in inductance .DELTA.L (sensitivity) which will result in an object being detected.  The length of subsequent measurement periods, defined by Nmeas oscillator cycles, is therefor periodically determined, compared to a reference value, and an output is provided if the compared difference exceeds a threshold value.  The desired minimum change in inductance .DELTA.L (sensitivity) may be automatically adjusted by determining an average magnitude change in inductance .DELTA.Lave caused by a plurality of vehicles and by then recalculating the number Nmeas of oscillator cycles based upon the average magnitude change in inductance.

Title: Sofa or armchair with adjustable sitting depth
Inventor: SUOMINEN KERSTI H
IPC: A47C/
Filed: 1991-03-06
Abstract: A sofa or armchair with adjustable sitting depth (7-8), which has a back rest (1), which can be detached and taken off and the distance of which can be changed and thus, the sitting depth can be changed, and to which belongs an adjusting and locking device (2), with which a stepless or adjustment with steps are locked. E.g.  the back of a sofa is traditionally fixed and almost all adjustment possibilities have been different solutions by cushions, which however, are not always satisfying when thinking of needs of different people. With this solution people of different lengths can adjust the sitting depth of a sofa or armchair fitting to themselves, which at the same time makes the sitting more comfortable and along with that reduces likelihood of back problems. Also the adjustable back rest gives new dimensions and possibilities for furniture design and product development.

Title: Fluid pulse generating apparatus
Inventor: STEINHARDT MICHAEL D
IPC: F16K31/04
Filed: 1992-11-06
Abstract: An apparatus for pulsing water flowing to a shower head includes a housing with a chamber, first and second water inlets to the chamber and a water outlet. The second inlet and the outlet are located through a wall of the housing at one end of the chamber. A valve has a plate with a plurality of apertures. The valve disposed within the chamber so that water flowing through the first inlet urges the valve into close proximity to the housing wall where rotational movement of the valve alternately opens and closes the water outlet.      That action creates a pulsed flow of water through the outlet.      Water flowing into the chamber through the second inlet moves the valve plate away from the housing wall permitting water to flow continuously from the second inlet into the outlet without being pulsed. A mechanism is coupled to the valve to produce the rotational movement.
